Can't get XAS 185 to load

I have an XAS 185 375 CFM that I use for sandblasting. I am unable to get the compressor to load properly when attempting to pressurize my sand pot.

I usually run between 90 - 110 lbs of pressure at the valve. In the past when it was working properly I would engage the remote and the pop-up valve in my sand pot would pressurize the system.

During this process you could hear the compressor gearing up when the load was put on it.

Now I am having problems getting the pop-up valve to seat itself on the first attempt. You can hear the piston in the pot trying to pressurize as if it wasn't getting enough pressure. Sometimes it takes several attempts to pressurize the system and when it does, it does not gear up.

I have rebuilt the pistons and other hardware on the pot, replaced air lines and the remote to no avail. I think it might have something to do with the linkage on the compressor. Any suggestions would be great as this has become very frustrating. Thanks
